For a more thorough explanation of how I go about an initial analysis, check out my blog post about it: https://www.biggerpockets.com/blogs/6815/45137-my-...

I had looked into my license years ago but was talked out of it but Im reaching a point where others will not dictate my decisions and I will make the changes I need to make.As I just read on one of the blog "4 steps to get off the sideline and take massive action "by Nathan brooks ...""

Here's an awesome blog I read about wholesaling.

If you wouldn't mind, look up a blog The Wizards of Real Estate, read that. 

Are there any real estate books or experts (with websites, blogs, etc) that talk about investing in real estate by using only cash? 

I've met a CCIM in person at an investor meetup here in DC, and have read a few comments by other CCIMs in blogs/forums - you guys seem to be at another level in terms of real estate professionalism and know-how, which I aim to be at one day myself.  

If you think something is fishy ask for a different name than the reference Read Landlording on Autopilot Read up on all the relevant BP blog posts

We don’t know any PMCs to recommend in the area mentioned, but since selecting the wrong PMC is usually more harmful than selecting a bad tenant, you might want to read our series about “How to Screen a PMC Better than a Tenant”:https://www.biggerpockets.com/member-blogs/3094/91877-how-to-screen-a-pmc-better-than-a-tenant-part-1-services-and-processesWe recommend you get management contracts from several PMCs and compare the services they cover and, more importantly, what they each DO NOT cover.

That seems counter-intuitive to what I've been getting from the blogs, forums, and podcasts. 

If you spend the next 3-6 months browsing the forums, reading the blog posts, and listening to the podcasts, you will be more than ready to do your first deal.
